Specification of Letters Patent.

Application filed September 25 1908. Serial No. 1545722.

To all whom it may concern:

Be it known that I, ERNEST E. SWEET, a citizen of the United States, anda resident of Detroit, in the county of Wayne and State of Michigan,have invented a new and Improved Valve, of which the following is aspecification.

My improvements relate to valves for controlling the exhaust ofexplosion engines,

moved to close one or another of the other openings.

It further consists in combination with a valve as above described, ofnieans for movopen the relief outlet.

ln the accompanyin drawing, Figure l is a view of one side of the valve.,Fig. 2 is a cross section on the line 22 of Fig. 3. Fig. 3 is an endview and Fig. 1 is a View of the side of the valve opposite to thatshown in Fig. 1.

Similar reference characters refer to like parts throughout the severalviews.

The valve consists of a body or shell, a movable member having a stemand an arm, a spring, and a lever. The body is composed of a cylindricalshell 1, closed at one end by the head 2. which head has a hub 3.Projecting from the shell are; tubular connections 4, 5 and G which maybe screw threaded to receive a pipe, or be smooth pipes may be slippedlongitudinally for adjustment. To hold the pipes in position the wallsmay be slotted as at 7 and screws 8 properly fitted to lock the parts.

Tightly fitting a seat at the edge of the opening at the end of theshell is a valve disk 10, having an arm 11 for turning the same. Themovement of the arm is limited by the lugs 12 on the edge of the shell.To this disk 10- is united a gate 13 which may be moved to cover theopening in either of the con nections 5 or 6. Upwardly extending guides14 hold the disk central with respect to the bore of the shell, when ofiits seat.

Projecting through and slidable in the hub 3 is a stem 15 which issecured to the disk 10 and which carries two pins 16 and 17. Betweenthese pins is the inner end of the lever 18 which is mounted between thearms 19 of a bracket that project from the head 2. A spring 20, betweenthe washer 21 on the stem and the hub 3, normally holds the valve disk10 onto its seat.

The operation of this construction is as follows, considering the pipe22 as the exhaust pipe of the engine, the pipe 23 connect ing to themuflier and the pipe 24 to the whistle. Should a gas explosion occur inthe exhaust pipe the excessive pressure of the gas will force the disk10 oil its seat and let the gas escape. As the use of the mufiler causesback pressure in the engine, it may be desirable at times to permit freeexhaust, which may be accomplished by moving the disk 10 ofi its seat bymeans of the lever 18. Normally the exhaust will pass through the shellinto the mufiler, but in case it is desired to change the course as forinstance to sound an alarm, the disk 10 may be turned by means of thehandle or arm 11, swinging the gate 13 from across the opening in theconnection 6 to across that in the connection 5. Where the exhaust gasesare employed to heat the interior of an inclosed carriage, the radiatormay connect to the pipe 24. I 1

Having now explained my construction, what I claim as my invention anddesire to secure by Letters Patent is 1* 1. A valve comprising acylindrical body having a head, and a plurality of connections for pipesand having the end opposite the head open, an outwardly movable disk toclose said open end, a stem connected to said disk and projectingthrough said head, and a spring to normally hold the disk in position.

2. A valve comprising a shell, connections projecting therefrom, a headfor said shell, a disk seated in an opening in the shell opposite thehead and having a stem passing through the head, and a. lever to movethe disk cit its seat- I 3. A valve comprising a body portion having aseries of apertures in one plane,
